this is just one of many links I found,,,they passed that hurdle yrs ago,,,the good ones produce far more than they take to make them,,,
Oh really? I admit it's been years since I read up on them...I'll check that out.
Thanks for the info!
Solar Panels Produce Far More Energy Than They Consume | EarthTechling
I will say I think that solar is a great idea in many places but it will never be a full replacement,,why every house in phoenix doesnt have solar panels confuses me
So I actually know someone who has family in Arizona. Their experience was they installed a large number on the roof, and some rodents of some sort, or birds, damaged the panel, resulting in a short that burned out the entire array. They lost all the money, and determined to never do it again. You have to have the array work for decades, for it to pay off. If something damages it before then, or if you wire something wrong, or it breaks for any reason... you are just screwed.
The companies that sell these, know to be very careful about what the warranty covers.
decades my ass,,,
and all those problems and warranty issue apply to any product
Well.... yes.
Decades.. yes. If you think you are going to make back the money on a solar panel in 5 years... you are insane.
Here in Ohio, the cost of electricity is 9 cents per kilowatt hour. A one kilowatt solar panel pack, is $1,230. Divide 1230 / 0.09 = 13666. Your 1 kw solar panels, need to produce at least 13,666 kilowatts, and that just covers the cost of the panels.
According to PVWatts Calculator (government website) I can expect these panels to produce roughly 1,320 kilowatts a year.
13666 / 1320 = 10 years.
Here's the kicker.... that's just for the panels. That doesn't include all the wiring, the power inverters, the batteries, the control system. Nothing. The panels alone, you are lucky to break even in 10 years. By the way, that doesn't include installation. Hope you are good climbing on your own roof, and drilling holes, and installing an electrical network.
For an entire off grid kit.... $3,166. Decades. That's how long it's going to take to break even.
So just to do some quick numbers for Arizona. $3,166 full kit / 11 cents per kwh = 28,780.
A 1 KW system in Arizona should produce on average about 1700 kwh per year.
28780 / 1700 = 17 years to break even. Almost two decades.
So once again, as it has for the last 10 years I've checked the numbers on solar panels, it still even to this day, takes decades to break even on them... assuming they continue to function for decades.
and all those problems and warranty issue apply to any product
While true... there is a huge difference between my computer, or my TV, and buying a solar panel.
I'm not trying to make money... or in this case... save money, by buying a TV. If my TV burns out after 10 years.... I'm good. I just buy another one. I wasn't trying to somehow make a return on my investment.
If my solar panels burn out after 10 years.... then I literally flushed money down the drain, for no benefit.
A TV, I gain a benefit from it, all during the time it is running, in the form of entertainment.
When a solar panel is operating, nothing is different in my life, than if there is no solar panel.
The only benefit to it's existence, is if I end up with a net saving of money, on my investment.
Thus if the solar panel does not last long enough to make that Return On Investment (ROI), then I honestly would have gotten more use from my money, by taking my cash outside, and setting on fire, and roasting a hot dog over the burning bills.
If the solar panels are damaged by dust, which shorts it out, or by rodents, or by a hail damage, or a tree limb, or anything else.... then I am out thousands of dollars for absolutely nothing.
theres a world of difference between decades and 5 yrs,,,
and as I said it makes sense in pheonix cant speak for ohio,,,
